It can be argued that young people’s socialisation into sport follows a general pattern of sampling, specialising and investing (Côté and Hay, 2002a). This paper develops research where we previously examined the key features of the sampling phase in the junior section of Forest Athletic Club (FAC) (Author 1 et al., 2003). Continuing our involvement in an ethnography of FAC in England we are now able to report and discuss key characteristics of the specialising phase that were evident through young people’s involvement at the club. These include a reduction in the number of sporting activities being pursued, enjoyment and success, the notion of deliberate practice and the influence of family, school and club support on those moving into the specialising phase. We note that while some of the key features of the sampling phase carried over to the specialising phase there were subtle differences in how they were practised. We report characteristics of the specialising phase that were not evident when observing and interviewing the same athletes when they were experiencing the sampling phase. In concluding we suggest how the quality of the sporting experience in the specialising years can increase the likelihood that young people will remain involved in sport.
